Hi,
In a project which I'm building i need to send and receive data between
a shift register (CD43034B) and a pic (pic16f877).
the SR is a bidirectional one and its role is to send and receive
a frequency to and from the PIC, whom checks the change in the frequency.
Therefore there's data been sent all the time, and I need to Know when the
end of transmission of the data from the SR is finished its cycle.
as far as I see in the data sheet of the SR there is no indication for such
thing.
does that need to be by a code which counts the
number of data packets which are received? counting clock cycles of common
clock of the components?
or maybe there's a better and easier way for finding that out?
Thanks, Amitai
